Sour and bitter can be good though. I love fresh onion as is. I ghetto caramelize it a bit to make it more palatable to my girlfriend though. For that you don't need to do a proper caramelization, getting the process going and adding a bit of sugar is enough.
I love to add vinegar too though. Vinegar, a bit of sugar, a bit of salt, some time on the pan, delish.
You don’t need to stick to stupid things such as labels at home. Do whatever you want. On the web, though… you’ll have the swift justice of the FOOD PURISTS VIGILANTES! (We’re still workshopping that name.)
